What is the difference between a multi-dimensional array and a jagged array?

Question

I recently read through the lesson on multi-dimensional and jagged arrays and I'd be lying if I said I was able to understand it. What exactly is a multi-dimensional array and what is a jagged array?

Answer 1

Jagged array can differ in size.
Multi dimensional arrays are all the same size

Jagged array

1,2,3,4,5
4,8,9

Muliti dimensional array
1,2,5,6
4,7,9,8
5,6,8,9
